The invention relates to a sliding mechanism and in particular to a sliding mechanism for an electronic device. Although specific embodiments may relate to a sliding mechanism for handheld electronic devices comprising radiotelephone functionality, other embodiments may not include radiotelephone functionality. Electronic devices may alternatively or additionally include audio/still image/video recording/playing functionality.
BACKGROUND OF THE INVENTIONElectronic devices, particularly user-portable radiotelephones (e.g. mobile cellular phones), often comprise two separate parts which can be slid between an open configuration in which a keypad, display and/or other user interface elements (including one or more connectivity ports e.g. USB ports) can be accessed and a closed configuration in which the keypad/display and/or other user interface elements are not accessible. More generally, sliding mechanisms for electronic devices allow a compact design facilitating user portability and may not necessarily hide user interface elements in the closed configuration.

The present invention includes one or more aspects, embodiments and/or features of said aspects and/or embodiments in various combinations whether or not specifically stated in that combination.
In order that the invention may more readily be understood, a description is now given, by way of example only, reference being made to the accompanying drawings, in which:—
In the following description, each feature which is identical to that of another embodiment is given the same reference number.
For ease of understanding, the following description includes relative terms such as “left” and “right”, but it is to be understood that the function of the invention is not limited to the specific orientations described.
The sliding mechanism 100 is intended for use with an electronic device such as a user-portable handheld radiotelephone (e.g. a mobile cellular phone), and includes a first part 102 and a second part 104.
The first part 102 is slidably movable relative to the second part 104 between a first configuration and a second configuration. In the first configuration, the first part 102 is positioned adjacent a left-hand end of the second part 104, as shown in
The sliding mechanism 100 includes a pair of guide portions for constraining the first and second parts 102, 104 to move between the first and second configurations. Referring to
Referring again to
The sliding mechanism 100 includes a locking device 112 to lock the first and second parts 102, 104 in a configuration intermediate the first and second configurations, as shown in
In use, the user is able to move the first and second parts 102, 104 between the first and second configurations by applying a force to those parts. For example, as seen in
The user may lock the first and second parts 102, 104 in the intermediate configuration shown in
The second part 104 of the sliding mechanism 200 includes a fourth magnetic element 212 positioned between, and spaced from, the second and third magnetic elements 108, 110, and arranged to attract the first magnetic element 106 and to bias the first and second parts 102, 104 towards a third configuration intermediate the first and second configurations, as shown in
The second part 104 includes a fourth magnetic element 312 positioned between, and spaced from, the second and third magnetic elements 108, 110, and arranged to repel the first magnetic element 106.
The sliding mechanism is shown in the first configuration in
In this way, the fourth magnetic element 312 serves to reinforce the bistable first and second configurations of the first and second parts 102, 104.
In the second and third embodiments, the existence of the fourth magnetic element may depend on the length of the first and second parts and on the size and/or strength of the magnetic elements.
In this embodiment, the third magnetic element 410 is arranged to repel the first magnetic element 106. In this way, the sliding mechanism 400 is not stable in the second configuration such that the first configuration is a monostable configuration.
In this embodiment, the first magnetic element 506 is integrally formed with the runner 518 of the first part 102, while the second and third magnetic elements 508, 510 are integrally formed with the guide rails 516 of the second part 104. Specifically, the magnetic elements are integrally housed at discrete locations internal to the guide rails 516 and the runner 518.
As seen in
Shielding may be provided in the electronic device to protect the electronic components of the device from being (e.g. detrimentally) affected by the magnetic field of the magnetic elements. In other embodiments, the magnetic elements may be electromagnetic elements. The biasing function described herein may be provided by permanent magnets of various types and may also be provided by electromagnetic/magnetic coatings applied to respective surfaces.
The applicant hereby discloses in isolation each individual feature described herein and any combination of two or more such features, to the extent that such features or combinations are capable of being carried out based on the present specification as a whole in the light of the common general knowledge of a person skilled in the art, irrespective of whether such features or combinations of features solve any problems disclosed herein, and without limitation to the scope of the claims. The applicant indicates that aspects of the present invention may consist of any such individual feature or combination of features. In view of the foregoing description it will be evident to a person skilled in the art that various modifications may be made within the scope of the invention.
While there have been shown and described and pointed out fundamental novel features of the invention as applied to preferred embodiments thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices and methods described may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements and/or method steps which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognized that structures and/or elements and/or method steps shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto. Furthermore, in the claims means-plus-function clauses are intended to cover the structures described herein as performing the recited function and not only structural equivalents, but also equivalent structures. Thus although a nail and a screw may not be structural equivalents in that a nail employs a cylindrical surface to secure wooden parts together, whereas a screw employs a helical surface, in the environment of fastening wooden parts, a nail and a screw may be equivalent structures.
